Breitling Navitimer 01

Mint condition Breitling Navitimer 01 automatic chronograph. It has just been returned from a full service with an independent watchmaker. It was originally purchased from authorised Breitling dealers Peter Jackson in 2011. It comes complete with all boxes and papers including the slide rule instructions, warranty booklet and all other peripherals. The Navitimer was first introduced in 1952, the Navitimer provided pilots and air crews with a highly innovative chronograph design. This particular one with this dial configuration is now discontinued and is a sought after model. For the first time, a watch featured a "navigation computer" capable of executing every calculation a flight plan requires. These include: multiplication, division, calculating ground speed, calculating miles per hour, calculating miles per minute, calculating fuel consumption, calculating rate of climb or descent, calculating the distance of climb or descent and nautical and statute mile conversion. This is a true professional instrument watch that has been adapted to today's even more strenuous requirements. Comes on original black leather strap with a little wear to it and Breitling pin buckle. It has an automatic winding Breitling calibre 13 movement which is the Breitling version of an ETA Valjoux 7750, with 25 jewel and operating at 28,800 vph and has a 42 hour power reserve. Nice tight rotating slide rule bezel and anti reflective sapphire crystal. Dimensions are: width is 43 mm excluding crown, 45 mm including crown and 48 mm lug to lug and thickness is 14.5 mm.
